If I remember correctly from my winter operations training, (20+ years ago) anti-icing fluid is
designed to fall off the wing before/at a certain speed during T/O, thus ensuring wing is (more or less) clean at rotation. It is meant to do its job until ice protection sys. takes over. That`s why diffferent thicknessess for different groups of A/C (read: T/O speeds)
